"For whatever reason AMD can’t seem to keep up with NVIDIA when it comes to the minimum framerate, even at lower resolutions. Certainly it’s obvious when the 1GB cards are video RAM limited at 2560, but if we didn’t have this data we would have never guessed the minimum framerates were this different at lower resolutions.

Finally we have a quick look at SLI/CF performance. CF seems to exacerbate the video RAM limitations of the 5000 series, resulting in the GTX 480SLI coming in even farther ahead of the 5870CF. Even at lower resolutions SLI seems to be scaling better than CF."
